Emphasizing Ride Comfort Inside, Steering Stability Outside.

1) The rigidity of the inside shoulder was tuned with fine grooves in a circumferential direction, for a smoother ride and greater comfort.

2) A blind groove was adopted for the wide rib on the outside shoulder, increasing rigidity.

AE51´s construction achieves light weight and high durability.

1. Layered Rubber for higher fuel economy

The two-layered treat compound, with a bottom rubber layer designed for higher fuel economy, delivers high efficiency without adversely affecting the tread´s grip performance.

2. Belt Cover

The belt cover firmly holds the tread portion, which must withstand the constant impact with the road surface, to maintain rigidity and maximize straight-line stability.

3. Turn-up Carcass Construction

The tyre´s construction - with the carcass tightly wound up to the shoulder to create a two-layered sidewall - achieves both light weight and high rigidity.

4. Bead Fillers

Bead fillers maintain sidewall stiffness. Different types of rubber were developed, component by component, with the goal of improving overall performance.

The construction improves the overall balance of performance as well as High-Speed Stability. The result is sharp steering response and a solid feel the driver can count on.
